Original No. 1,326,473. dated December 30, 1919. No. 351,248.

To all whom it may concern:

Be it known that I, GEORGE. W'. Bon/Ens, a citizen of the vUnited States, and resident of Somerville, in the county oi' Middlesex and State oi' Massachusetts, have invented certain new4 and useful Improvements in Plural-Record Plionograplis, of which the following is a speciiication.

, The present invention relates to machines of the sort known as phonograpiis, grapliopliones, or talking machines, which are adapted to reproduce sounds by the cooperation oi a stylus or other reproducing element withl a member, known as a record, which is carried by a moving part of the. machine and is so prepared that, when relative motion occurs between tlie record and the reproducing element, it may vi- Ibrate the latter in a manner Corresponding to sonorous vibrations. Such machines are generally provided with amplifying horns by which. the Volume ot' sound produced by the reproducing means is enlarged.

Theprincipal objects of my invention are three in number :-lirst, to provide improved means for carrying a plurality of records and reproducing the sounds recorded upon them in succession Without stopping themachine and Without shifting vtbe records; second, to make the record holder constitute part of the amplifying horn; and third to provide a machine in which tlie amplifying horn, or a part of it, is put in motion about its longitudinal axis. These and other, subsidiary and supplemental,y objects, the nature of which hereinafter appears, are accomplished by means fully 'disclosed and set forth in the following specification, in connection with the accompanying drawings. Such drawings, and the description in detail thereof, following, illustrate the embodiment of my invention in one concrete machine, Without being intended to limit the 'principles of lthe invention to any particular machlne or 1n anyway to restrict tlie scope of the in'venti0n.

In the accompanying drawings,

Figure l is a side elevation of the machine.

Fig. llis` an end elevation of t'nc machine viewed from the line fit-4c of Figs. l. and 2,

Application for reissue filed January 1-3, 1920. Serial Fig. 6 is a sectional elevation in detail on l an enlarged scale ofthe means for controlllngthe movements of the sound reproducing device.

Fig. 7 is a sectional View of a ball bearing l lioint constituting a detail of the amplifying iorn.

8 is a sectional View of a detail of construction.

The same reference characters indicate the saine parts in all the gures.

ln the drawings 1 represents a 'base or bed to which are secured the iframes @and 3 for supporting the record holder. 'Said frames are secured 'to the base at a distance apart determined bythe length' of the rec ord bolder, which 1s supported at its ends by the frames.

As appears best from Fig. 3, tl'ie record holder .is a tube or cylinder 4 adapted to support records which are indicated at 5,

and are shown here as being rings of relatively large dlameter and short axial eX- te-nt. vVlitliout limiting myself in any Way4 to the material from wliiclithe record holder may be made, I may state that I prefer to make it of somevmaterial which is light in Weight and .is at the same timeV tough and rigid. The material known as bakelite answers tli'ese requirements and is 'tbe material which li have Cliosen for this y other su pporting elements of the supporting vframes to occupy, of stiifening and strengthening the holder, and of providing gears for driving and being driven, as Will presently appear. The ring-f6 at the left hand end of the reco-rd holdinglcylinder has a lip 8 which is screwed into the 'eiid of the cylinder 4, and' a'shoulder adjacent to such lip ladapted to be brought up against the end of the cylinder. In its; outer surface this ring has a groove 9 which provides a runway'or track occupied by supporting and holding rolls which I am about to describe.

like other ring 7 has an inner lip or iiange winch `is threaded into the opposite end of the cylinder 4i and an outer concentric lip4 1Q adapted to lie outside o the cylinder' and to forni an abutment for the records at one erfl 'the holder. Said lip l0 has also a. iange or 'fin ll which ileinos one edge of the rnnwajgf' or trank ,Said ring' T also eqai'ppeii with a transvei web .l2-3 from Whit-,h there e" His a .e le concentric with the outer i finniieronee of the ring. on part o? whirh there is formed a Worin 15 and on anoilier art oi' Whioh is formed worin wheel or spira'i ge r lil. Said Worm and spiral gear are well 'shown in Fig, l.

The tra* and Il, apgroximate 'the 'forni .a een;s-Cn'enniterenco and thereby ein brace the minier bali of the reeorfl holding Cylinder. Each traine is quipped with two or more supporting-gj elements suoli as mils i? and; i8, shown in Fig. Li. which have ball bearing` mounts upon stntls i9 and 20, respectively. seein-er1 in the frames, and oeenpy the trae-lis or runways E) and l2, respostiijely, of the end rings of the record holder. These rolls in the two "frames provide a four point anti-friction support for the record holder whereby the .latter is enabefl to rotate smoothly. ereniy.. anti silently when driven.

livotaiiy conneeted with each supporting freine a holling frame,y such. holding fran'ies being inilioatetl at :21 and The' said holding' frames and supporting frames together. alien in the position shown in the drawings, forni' Conxpiete Cireinnterenees inolosing the oif 'the reeoiti holder. Tie members extending narailel to the axis o'l the recorfl holder Qass from the iframes at. one enfl to Corre v `ailing points on the frames at the other enc'i. Such members 'tor the ixetl snp'portine 'trai'nes are inairatexl at 23, 2li, am?n i, the latter Haring also as the pivot for the the tie members intliffateil at i2( swinging holding trames. While or fue swinging' iframes are anni The members 'o other functions beside e if ames or arras .2l and En :entiyv be shown.

'i abat against El Win-eh pass thronggii the overlapping portev` of the liftetl and swing ing trainee. bolts pase through sueh bushings enti tnfeaied into the tube.

The overlappi the and swinging: frames, 'v h a i rookie joint or l i' are eoni Ween Hemi of the bo ano a i of the vbushing miti a naar? l .length that the linnelile oint is not bound or gripped bet-Ween the bolt head and flange. Each ofthe holding frames or arms 2l, 22. carries one or more antieiiriotion rolls4 32 similar to the rolls l? and 18, occupying the tracks of the record .holder and serving an a1iti-tiiction means to confine the record holder to the supporting rolls. I do not intend to limit the invention to the use of antifriction means such as the rolls 17, 18, and as the supporting elements oonstituting the parts the supporting' .frames which direct-ljv engage the record holder, as it is within my contemplation to ase other elements than rolls,l which elements need not be movable relatively to the frames, or' even to omit the rolls or equivalents thereof altogether.

lWhen the holding trames are in position as shown in the drawings they are yieldingly helfl by spring oats-lies, one of which is shown particularly in Fig. 5. Such :atcb ronsis'ts ot a (log pivote tothe trame 2 near the upper @ncl thereof and having a sleeve 3% through which the shank of a latch extends. Said latch has a handle 36 and a toe 37 adapted to take. over a pin 38 on the adjacent end ot the swinging frame 2l. A spring 39 is interposed between the sleeve and the head 4,0 on the latch shank, thereby dra-Wing' the latch against the pin 38. An adjustable stop 4.1 is provided in the form Conveniently oi? a screw, threaded through a. iange on the end of the-swinging frame, and adapted to bear on a hardened anvil set into "he adiaeent part of the fixed ranie, saifl adjustable stop boing secured in its adjustments by a set screw 4Q. By these means the holding rolls 32 ot the holfgling' frames may be held always contiguous to the record holder. and be capable oi yielding in ease there should be any virregnlznities in the shape ot' the record holder. The latch (log 3 provided with a inger 43 adapted to stop against a pin li when the latch is releasef"L and turned aside. Each ot the fixed rarnes 2 and 3 has such a latch adapted to engage the cooperating swinging Tfr-aine.

The swirl" g frames may be swung up ont of the so as to leave the vrecord holffer nimhstrneteil anfl enable it to be picked np and, removed from the n'iaohine ttor purpose or' placing or removing records. Ywhen such swinging frames are turned np they move as a unit, being rigidly connected by the tie members previously descrihefl, and when turne-:i aside so far as to eiear the rexzortl holder they are arrested by vthe coming into Contact of compleniental shoulders 45, M3 on the fixed and swinging frames.

Une oit' the important features of the 1nvention is the provision for mounting a plarality of records upon one holder, so thatl the sounds reeorded on all the records may I on as to focus on the record surface.

vwith intervals of silence therevis another arm formed as a ring or eye in Which there is detachably mounted a, lens holder 67 carrying a magnifying lens. Said lens holder, as is indicated in Fig. G, is detachably connected by a screw thread with the internally threaded aperture of the ring-shaped arin 6d The cani projection or finger Si retains the lens holder in the position shown in Figs. 5 and 6 with respect to the record holder, the axis of the lens being radial to the holder and the .lens being at such a distance lfrom the record there- Preierably there is an index mark upon the lens which can be viewed by the yoperator at the same time that the record groove or a defi nite index niark on the record is seen through the lens. l The purpose ot the index mark on the lens is to secure an exact setting of the adjustable cani Enger at such a point with relation to the record grooves on two abutting records as to cause the stylus ot the sound reprodncer to be lifted from one record at or just beyond the ioint where the record of sound on that record ends, and be carried over the intervening blank portions of the records'and deposited in the groove of the next record near the point Where the record of reproducible sound vibrations on the latter begins. It 'is to be remembered that ordinarily there is a blank space at each end of a record Whereon either there is no record groove at all. or Where there may be a groove 1which is not oi such a character as to vibrate the reprodueer in such a Way as to produce musical or articulate sounds. The cani causes the repr-odncer to be held ont of Contact with the records while passing over the contiguous blank spaces of tivo adjacent records, as to avoid causing unnecessary and unpleasant scratchH ing or reaping sounds bet-Ween the reproduction ot the contents of two successive records. By blank spaces in this connec tion I means those parts of the records? nfhether provided with grooves or not, whereof contact and relative movement lwith and respect to the reproducer Will not produce sounds which torni any part of the indicated sound contents of the record. Each of the cani fingers is equipped with a lens having such an index, by the use of which each cani finger may be set with respect to the adjacent records as to canse the stylus to pass trom thedesired point on each to the desired point on the next, whatesf'er the Widths of the various records may 'bei Inakingit unnecessary that the record be of a uniform 'Width or of any standard Width. Thereby the machine is adapted to coninience and cont-inne the reproduction ot" the contents of the several records in succession between the ending of one and the beginning ofthe next, and

Meer:

Without producing preliminary or intermediete objectionable sounds.

This provision for adjusting the means 'for lifting the'reproduoing device in accordance with the varying widths of records vis a novel :feature with iny invention and is essential to the use of the invention.

The vibrations produced in the diaphragm et the sound box by the stylus are transmitted in the torni ot' sound vibrations through an amplifying horn. consisting ont the sections 70, 7l, 72, '73 and 7e. The first ot these sections is connected to the sound box through a coupling shown in detail in section in Fig. 6, such coupling being essentially a ball and socket joint consisting of a nipple on the sound box having a spherical exterior and a. sleeve 76 secured to the end of the horn section 70 and projecting therefrom in the form of a. segment of a spherical shellt This joint permits free play of the sound box 'when the latter is raised and lowered by the arm 53, which swings in a short arc.

The horn sections 70, 71 and 72 are all supported by thesection 7 3, Which is an elbow section having 'a base 77 or pedestah secured on the machine base l near the end of the record holding cylinder but independently of the cylinder and cylinder-supporting frames.

Horn section 7l is an intermediate seetion between the. iixed section 73 and that section 70 which is connected to the sound box, and is provided so that the connection between 'the moving sound box and the stationary horn section may be maintained in all positions ot the sound box. Conseqilentljn this intermediate section is connected at 'ts ends by swivel joints 78 and 7 9 with the adjacent sections.- The-se swivel joints are preferably equipped with bail bearings to maire the tric'tional resistance as little as possible. lthough the precise na,-

ture of the joint is not material to the more important aspects oi1 the invention, yet the joints are in themselves of sutlicien't importance to Warrant detailed description;

The joint 79 comprises a ring or Jerrule screwed on to the elbow end of the horn section 7l and having its -mouth internally threaded. Screwed into the internal thread of this -lierrnle is a sleeve S0 having an outwardly turned flange Si, in the side of Which ton-'ard the ferrule-"ZQ there is a ball race. notheiuball race is formed in the endet ferrule 79.' Between this errnle and the flange Sl is contained the inwardly turned iiange 82 ot a ring Q3 vv iicli extends outside of and beyond the iange 81 and is internally threaded tov inalre the screwed connection with the upper end of the horn section 73. A series of balls Se are contained between the terrnle 79 and ilange 82, and another series sp ectively.

of halls 85 are contained between the flanges 81 and S2. This hearing is oi' la character which permits separable' attachment to both of the sections connected thereby, and it also makes provision 'for adjustment so that the.

screwed upon the exterior of the section 70,' -a collar 57 screwed on the liornjsection 7l andan outer sleeveior-ring 78.

Ring S6 has a flange 88 projecting between the collar 87 and a lllange 89 on the sleeve or casing 7S. Between these Jflanges and the ring S7 are two sets o'lf halls 9() and 91 rev The collars 86 and Sare adjustable on thehorn sections 70 and 71 re'- spectively, and the ring; 78 is adjustable on the collar 87, thus adyustingr the hearings for the halls. Collar 86 is then locked by a key 92 on thel horn section 70 which is adapted to enter a notch 93 in the collar 86. The collar 87 and ring 78 are secured together Without possibility of impairment of their relative adjustments by means of a loc-k Washer 9d, a lock nut 94" and a key 95. The lock washer has an ear 91%? which enters a groove or keyWay in the collar `78; the lock nut-9a is screwed into the threaded interior of ring 78 far enough to hold the. Washer against the collar 87, and the key 95 is attached to the lock nut hy a screw 95 so as to project into a hole or-recess in the side of the section 71, all as shown in Fig. 7.

The two sections' 70 and 71 together areI at least as long as the entire length ot the maclnne, whereby the sound hoX may travel freely to the endy of the record most remote from the fixed section 73.

l have referred to the horn section 72 as a separate element. lt 1s separate Vtrom the section v71 only in the sense that it is` made separately for convenience of manu facture. Afterhemg assembled with the part 71 these two sections are inseparable and are not relatirely movable, so that they become n in effect one section.

` The final section 74 ot' the horn :is con tained in the record holder 4. It may he a- 'tlaring member, as shown in 'Fig'. 3,'to form a contmuatlon on a gradually enlarglng d1- anieter of thevother sections. butlit 1s not necessarily so made. It is Within the contemplation of luy-invention to leave out any *separate element like the conical tube 7st uf'ithin the record holder and leave the in* terior of said record holder entirely open whereby the outer Walls of the record holder form lalso the outer Walls of the terminal horn section 1Whether the record holder constitutes the horn with or Withoutv an in ternal member like the tube 74e, the fact is the same that the-terminal horn section eX- 'l tends though the record holder and is ro tated at all times While the machine is in operation.

A. close joint is made between the sleeve member 1e of the record holder, which |is the entrance portion of the terminal horn v section, and 'the stationary horn section 73. The abutting ends of this sleeve and the horn section are finished off on a plane perpendicular to the axis of rotation of the record holder so that practically a tight joint constitutes the support for the swinging horn sections and that it is mechanically independent of the terminal section. lt will he 'further understood, however, that there is a perfect continuation between all ot the horn sections and a gradual enlargement in diameter of the horn, having the same effect as a horn made in one piece with a straight axis and uniforn'xly rlaring side Walls. Finally, the inclusion of the terminal section in the record holder permits a saving in space and at the same time enables 'the terminal openingr ot'the horn to loe sutliciently large to deliver a great volume ot sound. l have found by experiments that a very long horn having a gradual taper to a terminal opening` ot comparatively lange diameter gives excellentell'ects in rthe reproduction o'f sound. My horn, although .made in sectifms7 is of substantially the same proj-mrtions as such a horn and secures the same etl'ects. lt is,'however, so built and arranged as to he economical of space and its final and largest section requires no provision ot' space whatever because it is Within the record holder. These horn sections should be as light as possible consistent with strength and the proper degree ot rigidity.

rlhe material which l prefer to use in makdesirable qualities lmownto me. I wish it to he understood, however7 that inl mentioning,` this material l have not intended tov linut myseltan any way to the employment of any particular material or to exclude the use of any other material than that named,

in case l should find it desirable to use other material.

The applying and removing of records is a simple matter. All that is necessary to be holder. Then,

'the lead screw for this purpose,

done primarily to change records is to die connect the sound 00X from the erinv 53 by removing pin 55, to swing the horn section 70, with thesound box, aside, to disconnect the latches 35, and swing hack the swinging holding frames 2l end 22 which ere so con neoted es to swing' in unison. The record holder is then entirely uncovered and may he lifted from the stationery oreille frames 2 and 3. In being; thus lifted, it comes sway easily from the horn section '73., es' there ere no overlapping joints between this horn section and the record holder.. The Worm gear 56 for driving the lead screw is removed from the Worm 15 by this swinging beck of the holding freine, so that such Worin gear does not obstruct the reniorsl of the record records elrcedy on the holder may be slipped oil" end others placed upon it, the key or spline l? eutoineticiilly slining the records properly. Thereupon the record holder may he replaced end the holding :traine returned.v In this replacement of the holder it is located in exactly the proper position by ineens of the rolls entering the track grooves 9 and l2, the tlenges flanking such grooves giving the holder the exactly coirect'posit-ioii end keeping it 'fro-ni moving endwise from suchV 1position.

When the holding freine is swung heck and is arrested by the shoulders e5, i6, citer swinging through about of arc, the heli nut 52`is then. at the side ot' the leed screr.T and is not supported by the screw. However, this nut'and the sound-hox-cuirying arm are not allowed to fell out of position, being held both hy :t strep 9G fastened, to the erin 53 end passing under the leed screwg and by e inger 97 which extends over the guide rod 28 on the opposite side oi seid rod from the erin 60. 'Although the strep 96 is near enough to the leed screw to retain the nut es described, yet is at the seine time fer enough below the leed screw to allow the nut 52 to oe entirely disengaged troni the threads of the screw preliminary to u. return of the' nut end sound box `to the heginning end of the record holder or to enr other point When e reproduction oit o record is to be commenced.

The described construction of nut und erin illustrated in Fig. 6 thus provides -for spositive feed of the sound box when reproducing the record, allows the nut and sound box to loe quickly returned to the starting position Without depending on n reverse-rotation 01 end holds the nut from felling away when the record retaining freine is swung aside.

The machine which l here illustrated is adapted to he mounted upon any sort of e table or stand, and accordingly may he mounled upon e cabinet edzipted to contain records and hielos-incN e compartment in which the driving motor is contained. l'
